BartSMP [9]

Explanation:

Wooho Physics my favorite subject! And my 100th answer :)

We will use the formula

\boxed{\tt{ Acceleration = \dfrac{v - u}{t}}}

  • Where v is Final velocity
  • And u is Initial velocity.
  • t is time taken.

In this question :-

  • u is 4 m/s
  • v is 6 m/s
  • t is 5 seconds

Applying the formula:-

\sf{ Acceleration = \dfrac{6 - 4}{5}}

\sf{ Acceleration = \dfrac{2}{5}}

So, Acceleration is 0.4 m/s² is the answer.

Hope it helps :)

A 900 N crate is being pulled across a level floor by a force F of 340 N at an angle of 23° above the horizontal. The coefficien
Olegator [25]

Answer:

0.958891203 m/s²

Explanation:

N = Weight of crate = 900 N

\mu = Coefficient of friction = 0.25

Force of friction acting on the force applied

f=\mu N\\\Rightarrow f=0.25\times 900\\\Rightarrow f=225\ N

Force used to pull the crate

F=340cos 23\\\Rightarrow F=312.97165\ N

The net force is

F_n=F-f\\\Rightarrow F_n=312.97167-225\\\Rightarrow F_n=87.97167\ N

Acceleration is given by

a=\frac{F_n}{m}\\\Rightarrow a=\dfrac{87.97167}{\dfrac{900}{9.81}}\\\Rightarrow a=0.958891203\ m/s^2

The magnitude of the acceleration of the crate is 0.958891203 m/s²
